FLUID-MEASURING APrARAT'Us.

Specification of Letters Patent. Patented Oct 17 1 916 I 1 Application filed March 17, 1915. Serial No. 15,110.

To all echom it may concern Be it known that I, OSCAR W. Axmansox, a citizen of the Kingdom of Sweden, residing at Rasunda, Sweden, have invented new and useful Improvements in'Fluid-Measuring Apparatus, of which the following is a specification.

This invention relates to apparatus for measuring fluids including a rotary measuring vessel divided into a number of cont partments and provided with an electromagnetically or mechanically operated locking device.

The object'of the invention is to provide an improved apparatus of this kind which may be used as a consumption controlling apparatus and in which the measuring op,- erations are automatically controlled by the measured fluid itself.

A further object of the invention'is to provide an apparatus of the said kind constructed and arranged to measure not only the units of volumes of the fluid consumed but alsoparts of such units.

The apparatus is especially adapted for measuring motor oil or lubricating oil to be used in connection with internal combustion engines and the like, for'measuring the water quantities supplied to steam boilers, and for other purposes.

T he invention consists, chiefly, in this that with the rotary measuring vessel is combined a receptacle adapted to receive the quantities of fluid measured off by the apparatus, and containing a float wh ch directly or indirectly releases the locking device of the measuring vessel when the sur-.

face of the fluid in the receptacle has sunken to a certain level.

In the accompanying drawing, forming a part of this specification, a construction form of the invention is shown partly in section and partly in elevation. I

Referring to this drawing, 1 designates a casing in which the measuring apparatus proper is arranged. The essential part of said apparatus consists of a vessel 2', divided into two compartments 201 and 202 .by means of. a partition 31. In the center of the vessel 2 said partition is enlarged to a cylindrical hub 32, by means of which the vessel is rotatably mounted on a. hollow shaft 20, forming a common fluid supply for the two'jcompartments of the vessel Inand 34 are provlded 1n the hub 32 and an opening 35 is provided in'thehollow shaft, the latter being arranged in such position that it registers with either of tions of thwessel 2. Each' compartment is provided with a separate outlet 21, 22 rearrangement being such that the onecompartment' communicates with the hollow shaft 20 when the outlet of the other compartment is open, as is'shown in the drawing. A pivoted valve 21 is'emp'loyed in the vessel 2 to control-the outlet 21,-and a. simi-' .the openings 33 and 3t in the locked posispectively in 'the wall ofthe vessel2, the

lar' valve 22 is employed complementary to the outlet Each of said valves is'closedl and normally kept closed by a spring, as.

shown, and each is, provided with'an arm 50 (see dotted lines), arranged outside the vessel2. As each of the valves approaches its I tionary projection 51, arranged in the casmg 1, with the result that the valve is lowermost position its arm engages a sta-.

opened. The vessel 2 is also equipped with the Y ordinary air vent valves 52. In such position the vessel 2 is maintained by a looking device 23, controlledby am electromagnet 27. The movement of the vfiessel 2 from such a position to thefollowin'g, after the one compartment has been fil edand the other has been emptied, willhe eflected by the weight of the fluid in the first mentioned compartment, as soon as thelockingdevice" T vided with a. window 4: and on one side isoperated to release the vessel 2; The con v thereof with a scale 5. With the receptacle 3 is connected a hydrometer '6 to determine the specific gravity of the fluid, in case it is desired to know the weight of the fluid measured.

The receptacle 3 contains a float 8 connected by a rod 9 and a lever 10 to a rod lfiadapted to control two contact springs 11, 12. Said springs are included in the'circuit of the electromagnet 27 and source of electric energy 27. This circuit also includes contact springs 30 designed to 'be alternately. controlled by pins 29 and 290, one complementary to each compartment, and connected with floats 291, 292, respectively. Conseone spring 80 will be pressed against the oner tc closethe circuit when the upper most compartment 1s filled with fluldi Said circuit will, thus, only be closed when both the contacts 11. 12 and the contacts 30 are closed. V

The contacts 11, 12 are closed when the surface of the fluid in the receptacle 8 has sunken to a certain level (zero position). The apparatus 2 will thus be maintained in locked position until the above said two conditions are fulfilled.

The apparatus 2 may be combined with an apparatus to count or register the number of measurements so that by referring to said apparatus a person in authority is enabled to ascertain the quantity of fluid passing tarough the apparatus. By observing. the

position of the fluid level in the receptacle 3, and subtracting the quantity of fluid in-v said receptacle from the quantity passed through theapparatus it is possible, Whenever desired, to obtain an exact value of the quantity of fluid consumed. By means of a float arranged in said receptacle, and

means actuablc by said float for controlling said electro-mechanical means and'thereby unlocking the vessel.

2. An apparatus for measuring fluids, comprising a rotary measuring vessel divided into compartments, electro-mechanical means for locking said vessel, floats arranged in said compartments of the vessel, and means actuable by said floats, alternately, for controlling said electromechanical means and thereby unlocking the vessel 3. An apparatus for measuring liquids, comprising a rotary measuring vessel divided int-o compartments, electro-mechanical means for locking said Vessel, a receptacle adapted to receive the fluid measured by said vessel, floats arranged in the compartments of the vessel, a float arranged in said receptacle,

means actuableby the floats in the compartments, alternately, for controlling the elec operated means and said source of electric energy, a float arrangedv in saidreceptacle, and means actuabl'e by the float for controlling the circuit to release the vessel from said electrically-operated means.

5. An apparatus for measuring fluids comprising a rotary measpring vessel divided into. compartments, electrically operated means for locking said vessel, a source of electric energy, an electric circuit containing the electricallyoperated means and said source of energy, floats arranged in the compartments of the vessel, and means actuable by said floats, alternately, for controlling the circuit to release the vessel from said electrically-operated means.

In testimony that I claim the foregoing as'my invention, I have signed my name in presence of two subscribing Witnesses.
